Instead of showing off her new baby bump, Jessica Simpson kept it under wraps.

Enjoying a romantic stroll along the beach with her fiancé Eric Johnson, the Texas-native donned a cowboy hat and multi-colored tunic during the couple’s Hawaiian holiday on Dec. 26.

Simpson, who gave birth to her first child Maxwell Drew on May 1, has been shedding the pounds (over 50!) with the help of Weight Watchers, where the singer-turned-designer serves as the newest spokesperson for the “Expect Amazing” campaign.
